The highest level of Tawheed (belief in the Oneness of God) is to render everything to Allah ﷻ, to recognise everything comes from Allah ﷻ and returns to Allah ﷻ, and to leave all your affairs to Allah ﷻ.
This doesn’t mean we don’t perform our work in society, or do what we must to be successful. Allah ﷻ helps those who help themselves. But it does mean that although we work and perform all our activities to the best of our abilities, we realise that success always comes from Allah ﷻ, that our life, health, and abilities are all gifts from Allah ﷻ, and nothing would be without Allah ﷻ.
